Since September 2020, Atlas Public Policy (Atlas) has partnered with the Southern Alliance for Clean Energy (SACE) to publish the annual Transportation Electrification in the Southeast report. This report benchmarks progress on transportation electrification in six states in the Southeast: Alabama, Florida, Georgia, North Carolina, South Carolina, and Tennessee. This is our fourth annual report and provides an update on progress from July 2022 through June 2023. While the Southeast is seeing strong growth across key EV measures, the region continues to lag behind the national average in EV adoption and charging infrastructure investment. The challenge moving forward is to ensure that state policies, electric utility regulations, unprecedented federal investments, and other public and private sector investments foster a thriving EV market that supports manufacturer and supply chain expansion, ensures consumers have equitable access to EV charging and vehicle ownership, and enables light, medium- and heavy-duty fleet operators to electrify.
